Front brake questions

[rebeldart]

Front right caliper locks up solid after applying brake, won't release without cracking the bleeder screw - need a new line or what ?

Need to clean the return port in the master cylinder. But it will happen again, unless the entire system from caliper to master cylinder is taken apart and cleaned, including the lines... It can even lock up if you don't apply the brake at all.

When was the last time you cleaned the master cylinder and especially the return hole? How about the caliper itself?

Thanks guys - just bought the bike a month ago and am doing a tear down/clean up. Doesn't sound too difficult ....................

Make sure that when you clean out that return port that you use a small wire strand from something like an 18 gauge wire to poke through it. Nothing else is small enough. If you don't see the wire going through into the MC, you'll want to get someone to drill you a new hole in that same position of the same size (do a search on my threads to find out what I'm talking about). I had a front MC that Suzuki for some reason never drilled out the return port hole. It caused my front brakes to lock up a couple of times before I finally found out why.
